You can put this solution on YOUR website!
y=ab^x is the form of an exponential function.
\n" ); document.write( "You have two points with values of x and y.
\n" ); document.write( "You need to find a and b.
\n" ); document.write( "Substiute as follows:
\n" ); document.write( "5=ab^1
\n" ); document.write( "7=ab^2
\n" ); document.write( "Divide the 1st into the 2nd to get:
\n" ); document.write( "7/5 = b
\n" ); document.write( "Substitue that into the 1st to get:
\n" ); document.write( "5=a(7/5)
\n" ); document.write( "a=25/7
\n" ); document.write( "EQUATION: y= (25/7)(7/5)^x
